240 HORSEPOWER KIT - SIDEWINDER and SRX

This simple kit will gain 40+ horsepower over stock and still run on 87 OCTANE!!!  Get your Sidewinder or SRX just ripping and get great fuel economy too!  Just send us your ecu for a quick reflash, and then install our awesome stainless steel muffler and clutch kit. 

The ECU tunes have the latest Super-Spool version which have very quick throttle response.  This kit includes a 3 bar map sensor which is required for the Super-Spool tunes.  The Hurricane Super-Spool tune is truly amazing!   

The Big Flow muffler is very trail friendly and fits excellent.  Its all stainless steel and polished, and even comes with a new flange gasket.  It is also about 6-7 lbs lighter than the stock muffler. 

Put the power to the ground with our Pro-Shift Clutch kit.  The custom cut helix makes the acceleration pull hard, and our Pro-Mag weights harness the extra power of the powerful tune. 

These kits are very powerful and very reliable.  You will be extremely impressed!!

Just send us your ecu for the Hurricane Performance tune, which we do right here.  Send it to  Black Diamond / Speed Shop Inc., 6238 318th Street Way, Cannon Falls, MN 55009.  We can usually flash it and ship it back the same day!!
